Hydraulic automatic valve is the fourth generation new product of pump control valve developed on the basis of digestion and absorption of micro resistance slow closing check valve, hydraulic control butterfly valve and multi-function hydraulic control valve. It has the functions of electric gate valve, electric butterfly valve and check valve. It can eliminate the harm of water hammer through quick closing and slow closing action, and can protect the safety of water pump and pipe network system.

The hydraulic automatic valve is mainly composed of valve body, butterfly plate, regulating valve, buffer hydraulic cylinder, etc., and the external part is connected by the regulating valve. When the pump is started, the valve plate is slowly opened to full open under the hydraulic action of the hydraulic pressure at the inlet end and the lower chamber of the driving hydraulic cylinder. When closing, under the action of backwater pressure of valve plate and piston upper chamber, the medium backflow will quickly close 90% and cut off most of the water flow, and then the slow closing of hydraulic cylinder damping will weaken the impact of return water pressure and eliminate destructive water hammer.

1. Small resistance: using directional valve control technology, large valve plate opening degree is high, resistance is small, resistance coefficient is 0.3-1.1
2. Small volume: the valve body adopts butterfly structure, and its volume is only 1 / 3-1 / 5 of that of multi-function hydraulic control valve with the same diameter
3. Light weight: the weight is only 1 / 3-1 / 5 of that of multi-function hydraulic control valve
4. Long service life: oblique sealing amplitude is adopted, with automatic compensation function for wear of sealing surface, and service life is greatly prolonged
5. Automatic control: the valve and water pump are interlocked through the medium in the pipe, and the pump valve is linked without manual intervention; 6. Energy saving and consumption reduction: the medium pressure is used to drive, without external power, and energy saving and consumption reduction is realized
7. Good sealing: the double sealing technology of soft and hard combination is adopted to effectively solve the sealing problem of large diameter valve and ensure "0" leakage for a long time
8. Easy to open and close: large valve plate adopts eccentric structure, small friction torque, easy to open and close
9. Easy maintenance: the control system components are outside the valve body, easy to debug, easy to maintain, online maintenance.

   Hydraulic automatic valve is a new type of control equipment of pumping station with the most novel structure, the most advanced performance and the most reliable operation at home and abroad. It is mainly used in the outlet pipe of automatic water supply and drainage pump station. Due to its small volume, it is especially suitable for the large diameter pipeline system of power, metallurgy, petrochemical, water department, municipal administration, environmental protection and other industries.

Technical performance
1. It has the functions of check-in, light load start-up, elimination of water hammer and so on.
2. The opening and closing of the valve is driven by the conveying medium and is automatically interlocked with the water pump, so it is very convenient to operate without personnel and external force.
3. Slowly open the pump: after starting the pump, the valve will not open until the inlet pressure of the valve reaches the preset value, which can reduce the pump starting current and ensure the safety of the motor and electric control system;
4. The energy saving effect is remarkable: the opening and closing parts are inclined butterfly plate, the water flow is smooth, and the loss along the way and local loss is very small;
5. The structure of butterfly valve has the characteristics of small volume and light weight, small space occupation and low civil engineering cost; the electro-hydraulic control system of hydraulic butterfly valve is cancelled to reduce cost, increase reliability and stability, reduce power consumption, and achieve the purpose of energy saving.
